Backend Developer

• Develop REST based API & Services that power our Salesperson to customer selling in stores.
• Assist in mentoring a team of skilled engineers while you get direct mentorship and support to grow your career to the next level.
• Design and Prototype. We love individuals who like to make things real. In writing the code, we often realize the more significant implications. Seniors typically set the path and standards for the team.
• Think in terms of telemetry and operations. Senior Engineers are thinking about more than just the code they are writing today but also whether that will be maintainable, testable, or supportable. And we build our applications to be easily monitored to catch potential issues before they impact our customers.
• On-call support - We care about our customers, so we build and support. We also care about you and ensure we have scheduled on-call rotation in our team. We are all human and need rest.
• Take a business problem and come up with the technical strategy (push vs pull etc real time vs batches sync vs async) within the team high level design and lead the implementation.
• Need minimal directions or guidance and collaborate with other engineers across teams working on the same or similar business problem.
• Ensure design or architectural deficiencies are addressed.
• Consistently lead delivery of valuable features
• Help elaborate requirements where necessary.
